ENGLISH ABSTRACT: Introduction: Globally Parkinson’s disease (PD) is the second most common neurodegenerative disease. Individuals with PD (IwPD) commonly exhibit a loss of axial rotation of the spine, which leads to reduced dissociation between the head, trunk, and pelvis (i.e., trunk-pelvis coordination (TPC)) during turning. This reduction in their stability during turning leads to an increased risk of falling. Individuals with PD also experience a decrease in their motor performance when a secondary task is added to the activity (i.e., dual-task (DT)). The effect of DTs on TPC during turning has not been researched in IwPD, but may hold important information into understanding the brain-body relationship in this population. Objective: This study set out the determine whether DT interference (DTI) affects TPC during turning in individuals with mild to moderate PD, and if this differs from apparently healthy age- and sex-matched individuals. Furthermore, to compare DTI of two types of DTs (specifically motor-motor (MM) and cognitive-motor (CM) DT conditions) on TPC during turning in individuals with mild to moderate PD compared to apparently healthy age- and sex-matched individuals. Lastly, this study set out to determine whether DT assessments during turning could be used as a prediction of fall risk based on fear of falling for individuals with mild to moderate PD. Methods: Descriptive characteristic of participants were collected. 22 IwPD (MDS- UPDRS: 57.86 ± 21.32 AU; age: 72.5 ± 4.35 yrs) and 23 healthy individuals (Control; 72.81 ± 4.40 yrs) were assessed during continuous 90°, 180° and 360° turns during single-task (ST) and two DT conditions. Specifically, participants had to complete a serial 3 subtraction task (CM DT) and carry a tray with cups filled with water (MM DT) while turning. The APDM Mobility Lab® inertial sensors were used to measure spatio- temporal turning variables, including DTI, TPC and TPC variability. Dual-task accuracy (%) was collected and fall risk was determined by the Falls Efficacy Scale-International (FES-I). Results: Interaction effects were found for turn duration, turn velocity, and turn angle (p < 0.01). Between-Group differences showed a higher no. of steps during 90° and 180° ST, MM and CM DT (p < 0.03); lower turn velocity during 90° ST, MM & CM (p < 0.04), and 180° MM DT (p < 0.04) in PD compared to Control. The 360° turn task revealed the most differences with an increase in no of steps for ST, MM & CM in PD compared to Control (p < 0.01); but Control did worse under ST 360° for Turn duration & Turn velocity (p ≤ 0.01). Under the 360° MM DT was worse in PD for turn duration, velocity, and angle (p ≤ 0.01). Whereas turn angle increased in Control for the 360° CM DT (p < 0.01). With-group differences were reported for the 90° turns with slower turn velocity in both groups (p < 0.01) in MM DT compared to ST. For the 180° task, an increase in no of steps in MM DT vs. ST and CM DT for PD and Control (p < 0.01) and turn duration increased in MM DT vs. ST for PD (p < 0.01); While turn velocity was slower in MM DT vs. ST and CM DT in PD (p < 0.01) and compared to ST in Control (p = 0.01). Again, most difference were recorded for the 360° turn, with the no. of steps and turn angle increasing in CM DT vs. ST for PD (p < 0.01); Also no. of steps was worse in MM DT vs. ST for PD (p < 0.01); and turn angle increased in ST vs. MM for Control (p< 0.01). Turn duration increased in ST vs. both DTs for Control (p < 0.01), with turn velocity slower for MM DT vs. ST and CM DT in PD (p < 0.04). Turn velocity was also worse in ST vs. both DTs in Control (p < 0.01), with CM worse than MM DT (p < 0.01). Turn angle increase under CM DT compared to MM DT in PD (p < 0.01), while MM DT increased in Control compared to ST and CM (p < 0.01). TPC mostly remained in- phase during both ST and DT conditions and showed little DTI in both groups. Mean TPC, TPC variability and DT accuracy revealed no interaction effect across the turn conditions (p > 0.05). TPC in Control group was worse during ST and MM DT compared to CM DT in Control (p < 0.01). The DTI on turn velocity (p < 0.01) and turn angle (p = 0.02) showed interaction effects, with the Control group demonstrating more DTI compared to PD during the 360° turn for both DTs, but mostly in the MM conditions (p < 0.05). However, MM compared to CM showed more DTI during all turning angles for both groups (p < 0.05). Multiple linear regressions showed that TPC variability during a 90° turn (MM DT) and 180° turn (CM DT) could accurately predict a fear of falling. Whereas DTI on TPC was related to fear of falling during a 90° turn (MM DT) and 180° turn (CM DT). Conclusions: Both groups mostly remain in-phase during turning activities of varying angles. Carrying a tray with two cups of water on top had greater DTI on most turning parameters, indicating a greater resource demand during this task and a possible influence of the restricted arm swing by holding the tray. The impact of the MM DT is thought to be due to increased compensatory strategies in IwPD, leading to decreased performance in turning parameters, but not in TPC. Lastly, TPC variability and DTI on TPC may aid in the prediction of a fear of falling, which in turn relates to fall risk. AFRIKAANSE OPSOMMING: Inleiding: Parkinson se siekte (PD) is wêreldwyd die tweede mees algemene neurodegeneratiewe siekte. Individue met PD (IwPD) toon gewoonlik 'n verlies aan aksiale rotasie van die ruggraat, wat lei tot verminderde dissosiasie tussen die kop, romp en bekken (d.w.s. romp-bekken-koördinasie (TPC)) tydens draai bewegings. Hierdie vermindering in hul stabiliteit tydens draai lei tot 'n verhoogde risiko om te val. Individue met PD ervaar ook 'n afname in hul motoriese uitvoering wanneer 'n sekondêre taak by die aktiwiteit gevoeg word (m.a.w. dubbeltaak (DT)). Die effek van DT'e op TPC tydens draai bewegings is nie in IwPD nagevors nie, maar kan belangrike inligting bevat om die brein-liggaam verhouding in hierdie populasie beter te verstaan. Doelwit: Hierdie studie het uiteengesit om te bepaal of DT interferensie (DTI) TPC beïnvloed tydens beurt in individue met ligte tot matige PD, en of dit verskil van oënskynlik gesonde ouderdom- en geslag-ooreenstemmende individue. Verder, om DTI van twee tipes DT's (spesifiek motor-motoriese (MM) en kognitief-motoriese (CM) DT-toestande) op TPC te vergelyk tydens omdraai in individue met ligte tot matige PD in vergelyking met oënskynlik gesonde ouderdom- en geslag-ooreenstemmende individue . Laastens het hierdie studie daarop gemik om te bepaal of DT assesserings tydens draai gebruik kan word as 'n voorspelling van valrisiko, soos baseer op vrees om te val vir individue met ligte tot matige PD. Metodes: Beskrywende kenmerk van deelnemers is ingesamel. 22 IwPD (MDS- UPDRS: 57.86 ± 21.32 AU; ouderdom: 72.5 ± 4.35 jr) en 23 gesonde individue (Kontrole; 72.81 ± 4.40 jr) is geassesseer tydens aaneenlopende 90°, 180° (ST) en 360° draaie (ST) en twee DT toestande. Spesifiek, deelnemers moes 'n reeks 3 aftrektaak (CM DT) voltooi en 'n skinkbord met koppies gevul met water (MMDT) dra terwyl hulle draai. Die APDM Mobility Lab®-sensors is gebruik om ruimte- temporele draaiveranderlikes, insluitend DTI, TPC en TPC veranderlikheid, te meet. Dubbeltaak akkuraatheid (%) is ingesamel en valrisiko is bepaal deur die Falls EfficacyScale-International (FES-I). Resultate: Interaksie-effekte is gevind vir draaiduur, draaisnelheid en draaihoek (p < 0.01). Tussen-groep verskille het 'n hoër nr. van treë tydens 90° en 180° ST, MM en CM DT (p < 0.03); laer draaisnelheid tydens 90° ST, MM & CM (p < 0.04), en 180°MM DT (p < 0.04) in PD in vergelyking met Kontrole. Die 360 °-draaitaak het die meeste verskille geopenbaar met 'n toename in aantal treë vir ST, MM & CM in PD in vergelyking met Kontrole (p < 0.01); maar Kontrole het swakker gevaar onder ST 360° vir Draaiduur & Draaisnelheid (p ≤ 0.01). Onder die 360° was MM DT erger in PD vir draaiduur, snelheid en hoek (p ≤ 0.01). Terwyl draaihoek toegeneem het in Kontrole vir die 360° CM DT (p < 0.01). Met-groep verskille is gerapporteer vir die 90° draaie met stadiger draaisnelheid in beide groepe (p < 0.01) in MM DT in vergelyking met ST. Vir die 180°-taak was daar ‘ntoename in aantal treë in MM DT vs. ST en CM DT vir PD en Kontrole (p < 0.01) en beurtduur verhoog inMMDT vs. ST vir PD (p < 0.01); Terwyl draaisnelheid stadigerwas in MM DT vs. ST en CM DT in PD (p < 0.01) en in vergelyking met ST in Kontrole(p = 0.01). Weereens is die meeste verskil aangeteken vir die 360°-draai, met die nr. van treë en draaihoek wat toeneem in CM DT vs. ST vir PD (p < 0.01); Ook nie. van treë was erger in MM DT vs. ST vir PD (p < 0,01); en draaihoek verhoog in ST vs.MM vir Kontrole (p < 0.01). Draaiduur het toegeneem in ST vs. beide DT's vir Kontrole(p < 0.01), met draaisnelheid stadiger vir MM DT vs. ST en CM DT in PD (p < 0.04). Draaisnelheid was ook slegter in ST vs. beide DTs in Kontrole (p < 0.01), met CM slegter as MM DT (p < 0.01). Draaihoektoename onder CM DT in vergelyking met MM DT in PD (p < 0.01), terwyl MM DT in Kontrole toegeneem het in vergelyking met ST en CM (p < 0.01). TPC het meestal in-fase gebly tydens beide ST en DT toestande en het min DTI in beide groepe getoon. Gemiddelde TPC, TPC-veranderlikheid en DT- akkuraatheid het geen interaksie-effek oor die draaitoestande getoon nie (p > 0.05). TPC in Kontrolegroep was erger tydens ST en MM DT in vergelyking met CM DT in Kontrole (p < 0.01). Die DTI op draaisnelheid (p < 0.01) en draaihoek (p = 0.02) het interaksie-effekte getoon, met die Kontrolegroep wat meer DTI gedemonstreer het in vergelyking met PD tydens die 360° draai vir beide DT's, maar meestal in die MM toestande (p < 0,05). MM in vergelyking met CM het egter meer DTI tydens alle draaihoeke vir beide groepe getoon (p < 0.05). Veelvuldige lineêre regressies het getoon dat TPC-veranderlikheid tydens 'n 90°-draai (MM DT) en 180°-draai (CM DT) 'n vrees vir val akkuraat kan voorspel. Terwyl DTI op TPC verband hou met vrees om te val tydens 'n 90°-draai (MM DT) en 180°-draai (CM DT). Gevolgtrekkings: Beide groepe bly meestal in fase tydens draaiaktiwiteite van verskillende hoeke. Om 'n skinkbord met twee koppies water bo-op te dra, het groter DTI op die meeste draaiparameters gehad, wat 'n groter hulpbronaanvraag tydens hierdie taak aandui en 'n moontlike invloed van die beperkte armswaai deur die skinkbord vas te hou. Die impak van die MM DT word vermoedelik te wyte aan verhoogde kompenserende strategieë in IwPD, wat lei tot verminderde prestasie in draaiparameters, maar nie in TPC nie. Laastens kan TPC-veranderlikheid en DTI op TPC help met die voorspelling van 'n vrees om te val, wat op sy beurt verband hou met valrisiko.
